What must happen before acetyl-CoA can be formed during respiration?

Answer 1

this is the answer

The glucose is broken down into 2 molecules of pyruvate, which are two smaller molecules. A net yield of 2 ATP and 2 NADH result. Each pyruvate is connected to a coenzyme. The resulting molecule is called Acetyl CoA. That reaction also gives off 2 molecules of C02. The Acetyl CoA enters the Krebs Cycle, from which (through a series of steps), 2 more ATP, 6 NADH, 2 FADH2, and 6 CO2 are formed. The 6 NADH and FADH2 (which are coenzymes) move on to the electron transfer chain. Here, they give up their H+ and electrons to the chain. The electrons reduced the proteins on the chain, allowing H+ from outside the cell to be brought in. Bringing this H+ into the cell builds up the concentration. When the concentration gets high enough, the H+ wants to go back out of the cell. The only way to do this is through the ATP synthase. When is passes through this, the synthase combines an ADP with an inorganic phosphate, forming ATP. The typical yield is 32 ATP from this, giving a total of 36 when you add in the ATP from glycolysis and the Krebs cycle.

Answer 4

Before acetyl-CoA can be formed during respiration, pyruvate must be converted into acetyl-CoA through a series of enzymatic reactions in the mitochondrial matrix. This process involves the decarboxylation of pyruvate by the enzyme pyruvate dehydrogenase complex, which also generates NADH as a byproduct. Acetyl-CoA can then enter the citric acid cycle for further energy production.

Answer 5

Two phosphate groups must be attached to glucose.

Answer 6

Before respiration the food molecules are broken down and converted to glucose. This breaking down of food molecules results in the production of energy.

Answer 7

Dehydration synthesis must occur before two glucose molecules can join together. When organisms have extra glucose left over, they bond it together to create a polysaccharide.

Answer 8

they must break down first

Answer 9

Fermintation
